Answer: X represents C) 3p2

Given:

Atomic number of an atom = 14

Partial electron configuration = 1s²2s²2p⁶3s²X

To determine:

The identity of X

Explanation:

Based on the Aufbau rule, the order in which the orbitals fill up based on energetic considerations is:

1s 2s 2p 3s 3p 4s 3d 4p ....

maximum # electrons in s orbital = 2, p = 6,  d = 10 and so on

Since 3p would follow the 3s orbital, in this case we will have the full configuration as:

1s²2s²2p⁶3s²3p²

Ans c) X = 3p²

The reaction rate is k[Ce4+][Mn2+] for the following reaction: 2Ce4+(aq) + Tl+(aq) + Mn2+(aq) → 2Ce3+(aq) + Tl3+(aq) + Mn2+(aq W
sdas [7]

Answer:

Manganese (II) ion, Mn²⁺

Explanation:

Hello,

In this case, given the overall reaction:

2Ce^{4+}(aq) + Tl^+(aq) + Mn^{2+}(aq) \rightarrow 2Ce^{3+}(aq) + Tl^{3+}(aq) + Mn^{2+}(aq)

Thus, since manganese (II) ion, Mn²⁺ is both at the reactant and products, we infer it is catalyst, since catalysts are firstly consumed but finally regenerated once the reaction has gone to completion. Moreover, since inner steps are needed to obtain it, we can infer that the given rate law corresponds to the slowest step that is related with the initial collisions between Ce⁴⁺ and Mn²⁺

Best regards.
